TRIGGER GUARD FOR REVOLVER Filed Nov. 23, 1962 Unite The present invention relates to firearms and more particularly to a trigger guard and to the means for securing the same to a revolver.

The trigger guard of firearms is generally secured to the stock or lock frame by means of screws. This not only requires the end of the trigger guard to be extended but it also requires surfaces for receiving these extensions and bores for the mentioned screws, as well as these screws themselves.

it is an object of the invention to provide a trigger guard with means for securing it to a revolver frame in a manner which renders the previous securing means as mentioned above superfluous and which thus also saves the time and expense of producing them. The new securing means according to the invention have the further advantage that they facilitate the assembly and disassembly of the revolver and insure a secure clamping connection of the trigger guard to the revolver frame by means of a single screw.

For attaining these and other objects and advantages, the front end of the trigger guard is provided with a projection which engages into the frame of the gun and has a wedge-shaped recess into which the conical end of a setscrew engages which is inserted into the frame, while at its other end the trigger guard is provided with a nose like projection which extends over the edge of the frame. This nose on the trigger guard and the adjacent edge of the grip portion of the frame are preferably provided with corresponding beveled surfaces which are directed toward the inside of the gun so that, when the setscrew is screwed in, the trigger guard will be drawn inwardly against a seat on the grip portion of the frame.

This design of the trigger guard has the further ad-' vantage that it permits the trigger spring to be easily installed and mounted so as to require very little space by being inserted into a recess in the upward projection on the front end of the trigger guard. This trigger spring: tends to maintain the trigger in its normal inactive posi-- tion.

The present invention will now be described in greater detail with reference to a preferred embodiment thereof as illustrated in the accompanying drawing which shows a side View, partly in section of a revolver.

The trigger guard 1 of the revolver has near its front end an upward projection 2 which is inserted into a recess in the frame 3. This projection 2 has a wedge-shaped aperture in the form of an unsymmetrically conical bore 4 into which the conical end 5 of a setscrew it engages states atent ice which is accessible from the outside. At the other end, trigger guard it is provided with a noselike projection 7 which extends over the edge of wall 8 of the grip frame 9 which may be an integral part of frame 3. By tightening the setscrew 6 trigger guard 1 is pressed by the projection 2 upwardly and also toward the rear so that underneath its nose 7 it engages firmly against the edge of the wall 8 of the grip frame 9.

This nose '7 is provided with a surface 18 which is directed inwardly and wall 8 of frame 9 is provided with a corresponding beveled surface 19. These beveled surfaces engage with each other and insure a secure seat of trigger guard 1 on frame 9.

The projection 2 is provided with a recess ill in which a trigger spring 11 is mounted on a pin 12. One arm of this spring rests on the trigger guard 1., while its other arm acts upon a nose 13 on the trigger 14, whereby the latter is pressed toward its normal inactive position.

in the particular construction of the revolver, as illustrated, setscrew 6 also serves as a pivot pin for an arm 15 which carries the support or bracket 1'16 of the cartridge drum 1?.

Although my invention has been illustrated and de scribed with reference to the preferred embodiment thereof as applied to a revolver, I wish to have it understood that it is in no way limited to the details of such embodimerit but is capable of numerous modifications within the scope of the appended claims and also to its application to firearms other than revolvers.

Having thus fully disclosed my invention, what I claim 1. In a revolver having a main frame with a recess therein, a grip frame secured to said main frame, a trigger guard having an upward projection near one end thereof fitting into said recess, said projection having a conical recess extending in the longitudinal direction of said trigger guard, a setscrew for securing said trigger guard to said main frame inserted into said main frame and having a conical end engaging into said conical recess, and a noselike projection on the other end of said trigger guard extending over the inner edge of the wall of said grip frame.

2. In a revolver as defined in claim 1, in which said noselike projection on said trigger guard and the inner edge of the wall of said grip frame have corresponding beveled surfaces directed toward the inside of the revolver.

3. In a revolver as defined in claim 1, in which said upward projection on said trigger guard has a recess, and a trigger spring inserted into said recess.

4. in a revolver as defined in claim 1, having a cartridge drum rotatable within said main frame, a bracket for supporting said drum, and an arm on said bracket having a bore, said screw extending through said bore and forming a pivot pin for pivotably mounting said arm.

1. IN A REVOLVER HAVING A MAIN FRAME WITH A RECESS THEREIN, A GRIP FRAME SECURED TO SAID MAIN FRAME, A TRIGGER GUARD HAVING AN UPWARD PROJECTION HAVING A CONICAL RECESS EXTENDING IN THE LONGITUDINAL DIRECTION OF SAID TRIGGER GUARD, A SETSCREW FOR SECURING SAID TRIGGER GUARD TO SAID MAIN FRAME INSERTED INTO SAID MAIN FRAME AND HAVING A CONICAL END ENGAGING INTO SAID CONICAL RECESS, AND A NOSELIKE PROJECTION ON THE OTHER END OF SAID TRIGGER GUARD EXTENDING OVER THE INNER EDGE OF THE WALL OF SAID GRIP FRAME.
